🔐What Is a Blockchain Wallet?

A blockchain wallet is a tool used to store and manage digital assets such as NFTs and in-game items.

Simply put, a blockchain wallet is like a personal safe that holds your game items.

Without a wallet, you cannot directly own or use assets in blockchain-based games or services.

💡 Important Things to Know

The following information is very important. Please read carefully.

🎮 NFT heroes and items created or traded in the game can only be owned when a wallet is connected.

🔑 NFT heroes and items are not owned by the game company, but are directly owned by the player’s wallet.

✍️ When trading or transferring NFTs, you must approve the transaction (sign) in your wallet.

This approval process confirms that the action is being performed by the player’s own decision.
